Optimum Structural Design of Catalytic Muffler Based on Set-based Design Method

Abstract

A catalytic muffler design is required the structure that makes emission gas flow smoothly in the muffler for improving the purification efficiency. This paper focuses on the design environment including uncertain design information and applies a preference set-based design method to the catalytic muffler design in the design phase. The design method can obtain a ranged set of design solutions that satisfies performance requirements by representing uncertain design information as ranged sets.
